摘要

为解决人工手持雷达天线进行隧道衬砌质量无损检测存在的测线偏移、仪器脱离隧道表面、往复作业检测效率低、安全隐患多等问题，研制一款可实现单次全断面机械化作业的隧道衬砌质量检测台车。该台车集成多级伸缩机械臂及九通道隧道质量检测系统，具有单次多线机械化同步检测、多通道雷达天线数据采集控制、雷达天线与隧道壁自适应、里程综合定位及视频采集等关键技术，并已在湖北郑万高铁某隧道使用，检测效果良好。相较于传统单次单线检测方式，检测效率由15 h/km提高至1 h/km；雷达天线自适应功能保证仪器紧贴隧道表面，检测连续可靠；同时，九通道隧道质量检测系统的应用，一定程度上实现了衬砌质量检测的信息化。

Abstract

When nondestructive inspection is carried out on the tunnel lining quality by the operation mode of handheld radar antenna, many problems such as line deviation, instrument separation from tunnel surface, low detection efficiency of reciprocating operation and many potential safety hazards, exist. As a result, a tunnel lining quality detection trolley which can realize single fullsection mechanized operation is developed. The trolley integrates a multistage telescopic robotic arm and a ninechannel tunnel quality detection system, and has key technologies such as single multiline synchronous detection, multichannel radar antenna data acquisition control, antenna radar and tunnel wall adaptation, mileage integrated positioning and video acquisition. It has been applied in a tunnel of ZhengzhouWanzhou Highspeed Railway in Hubei Province, and good detection effect has been achieved. Compared with the traditional single line detection method, the detection efficiency is improved from 15 h/km to 1 h/km. On the other hand, the radar antenna adaptive function ensures that the instrument is close to the tunnel surface, and the detection is continuous and reliable; and the application of ninechannel tunnel quality inspection system can realize the informatization of tunnel lining quality detection to some extent.
